vs QT Use QGuiApplication::screens报错

严重性    代码    说明    项目    文件    行    禁止显示状态 错误    C4996    'QDesktopWidget::availableGeometry': Use QGuiApplication::screens(

解决方法：

QRect rect = w.frameGeometry();
    QDesktopWidget desktop;
   // QPoint centerPoint = desktop.availableGeometry().center();
   // QPoint centerPoint = QGuiApplication::screens;
    QPoint centerPoint= QGuiApplication::primaryScreen()->availableGeometry().center();
    rect.moveCenter(centerPoint);
    w.move(rect.topLeft());

即可居中显示咯
